CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority under 35 U.S.C. 119 (f) to the application for European Community Plant Variety Rights which was filed for the instant plant variety on Dec. 18, 2014, File Number 2014/3489.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar of hardy Dianthus, commonly known as Garden Pink, which is grown for use as a flowering plant for pots and containers and for planting in the garden and landscape. The new cultivar is known botanically as Dianthus×allwoodii and will be referred to hereinafter by the cultivar name ‘WP15 VAL11’.

‘WP15 VAL11’ is a complex hybrid plant that is the product of a long term breeding program conducted in a cultivated area of Houndspool, Dawlish, Devon, United Kingdom. ‘WP15 VAL11’ was selected in 2011 for its double delicate light pink flowers with a fuchsia eye, ruffled petal edges, strong, sweet fragrance and glaucous blue-green foliage.

‘WP15 VAL11’ arose and was selected as a seedling which resulted from the controlled pollination of two prior selections of Dianthus. The male parent is Dianthus code name ‘MOW 02.09’ (unpatented and unreleased) and the female parent is Dianthus code name ‘VAL 05.15’ (unpatented and unreleased). The male parent and female parent had both grown within the inventor's stock of breeding lines.

Asexual reproduction of ‘WP15 VAL11’ was first accomplished in 2011 in a cultivated area of Houndspool, United Kingdom using the propagation method of shoot cuttings. ‘WP15 VAL11’ has been determined to be stable and reproduces true to type in successive generations of asexual propagation.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of the new Dianthus variety ‘WP15 VAL11’ showing colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety ‘WP15 VAL11’.

Photographs were taken in August 2015 in Oxnard, Calif. of five-month old plants which have been grown outdoors in 1.5-liter containers. No chemicals were used to treat the plants. All photographs were made using conventional techniques and although colors may appear different from actual colors due to light reflectance they are as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new cultivar ‘WP15 VAL11’. Data was collected from plants grown in 3-liter containers under an unheated glasshouse in Houndspool, United Kingdom. The color determinations are in accordance with the 2001 edition of The Royal Horticultural Society Color Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.

COMPARISON WITH PARENTAL LINE AND KNOWN VARIETY

‘WP15 VAL11’ is distinguishable from the male parent as follows. Whereas the plant shape of ‘MOW 02.09’ is similar to ‘WP15 VAL11’, the vegetative habit of the two varieties is very different. ‘MOW 02.09’ is much less vigorous than ‘WP15 VAL11’ and exhibits shorter flower stems and a tighter habit. In addition, the flower color of ‘MOW 02.09’ is white with a maroon eye.

‘WP15 VAL11’ is distinguishable from the female parent as follows. Whereas the flower shape of ‘VAL 05.15’ is similar to ‘WP15 VAL11’, the vegetative habit and the flower color of the two varieties are very different. ‘VAL 05.15’ has wider leaves than ‘WP15 VAL11’ and ‘WP15 VAL11’ exhibits many more flower stems and a better overall shape. In addition, the flowers of ‘VAL 05.15’ are larger and medium pink in color with a darker eye than that of ‘WP15 VAL11’.

The variety of Dianthus considered to most closely resemble ‘WP15 VAL11’ is Dianthus Plant Named ‘Devon Flavia’ (U.S. Plant Pat. No. 15,903). In comparison with ‘Devon Flavia’, ‘WP15 VAL11’ is approximately one-third taller and bears flowers which are approximately one-third greater in diameter. Whereas the flowers of ‘Devon Flavia’ are bicolored pink and reddish-purple in color, the flowers of ‘WP15 VAL11’ are light pink and fuchsia in color. 

I claim:
 1. A new and distinct cultivar of Dianthus plant named ‘WP15 VAL11’ as described and illustrated herein.
